    /* ACCENTS FOLLOW THE GROUND. This block must flip the accents as well as the eight surface
       and ink tokens: an accent left at its dark-ground value on this light ground measures
       primary 2.04:1, beak 2.29:1, status-ok 1.53:1 against #f5f0e6, where the bar for text is
       4.5:1. Not "too pale" — the right colours for the wrong ground.

       Hue and saturation are preserved; only lightness moves, to the first value that clears the
       bar. Dark mode is untouched.

       THE HOVER STEP FLIPS DIRECTION AND THAT IS THE POINT. -deep is darker than -primary in both
       modes, but on the navy ground darker means LOWER contrast (7.82 -> 4.49) and on the cream
       ground it means HIGHER (4.51 -> 6.53). The step itself stays comparable: 1.74:1 dark,
       1.45:1 light. A light block that copied the dark relationship would have made the hover
       vanish. */

       is 1.23:1 and invisible, which is the accents-follow-the-ground defect this block exists
